I could not tell, the deal is, after about 3 days of play and normal auto saving, the next time I go to turn it on it all of a sudden starts from the beginning. Loosing all progress, what is wierd is that the track times and speed cam speeds i've posted are all still there, except nothing is actually completed and I have to start all over from the beginning.
The first time this happened the game froze up, I sat there for 5 minutes seeing if it would stop, anyways had to manually shut the game off, then when I started it all my saved progress was gone, the second time it happened nothing had froze or anything, I was just playing it, quit, then started playing it again hours later and once again starting completely over. This has never done this on any other NFS i've ever had, I've had every NFS since the original on the panasonic 3DO
